7.6 Anchoring
Columns
• Use the base plate on the column as a guide, drill each hole in the concrete
approximately 6” deep with
the rotary hammer drill D.20.
To assure full holding power,
do not ream the hole or allow
drill to wobble;
• After drilling, remove dust
thoroughly from each hole
using compressed air and/or
wire brush. Make certain that
the column remains aligned
with the chalk line during this
process;
• Assemble the washers and
nuts on the anchors then
tap into each hole with a
hammer until the washer
rests against the base plate.
Be sure that if shimming is required that enough threads are left exposed;
• If shimming is required, insert the shims as necessary under the base plate
so that when the anchor bolts are tightened, the columns will be plumb;
• With the shims and anchor bolts in place, tighten by securing the nut to
the base. DO NOT use an impact wrench for this procedure;
• Before anchoring the fi nal column, lay out the cover plate and use it for
reference. Check measurements and alignment before drilling.
• Anchor the fi nal column as outlined in above steps;
• Check to make sure that the columns for square-ness and plumb are as
shown in the fi gure 9.
The requirements for column’s square-ness and plumb must be
adhered to. Failure to do so could cause lift failure resulting in
personal injury or death.
